AI Security Review
scanned 6d ago · by lpm-firewall-aiThe browser preview initializes PostHog automatically during module evaluation and sends analytics to a tscircuit-controlled host. The source exposes a global opt-out but no user-facing disclosure, so this is suspicious runtime telemetry rather than evidence of credential theft.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Importing the preview entry in a browser.
Impact
Browser telemetry may be sent to the package publisher’s analytics endpoint without user-facing disclosure or consent.
Mechanism
The shared chunk calls PostHog initialization at module scope and configures its API host; a global opt-out flag is available.
AI rationale
The browser preview initializes PostHog automatically during module evaluation and sends analytics to a tscircuit-controlled host. The source exposes a global opt-out but no user-facing disclosure, so this is suspicious runtime telemetry rather than evidence of credential theft.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The exported preview entry imports the shared chunk that contains the telemetry initialization.
- The shared chunk initializes PostHog during module evaluation in browsers; telemetry is disabled only by a global flag or a localhost check.
- PostHog is configured to send to https://postpig.tscircuit.com.
Evidence against
- The package provides browser-based circuit preview and runner components, for which runtime analytics can be relevant.
- The inspected source shows no install lifecycle scripts or automatic credential theft.
